Please help and show all steps

Find the equation in standard form which passes through (-1,4) and (0,9)

Answer 1

slope = (y2-y1)/(x2-x1)= 5/1 =5
standard form: y=mx+b
pick a point (0,9)===> 9=b
y=5x+9

Answer 2

m=(y1-y)/(x1-x)
slope m=(9-4)/(0-(-1))
m=5/1=5
now you use ANY point to build your equation

Answer 3

y-9=5(x-0)
y=5x+9
standard form would look like:
5x-y+9=0
